DISH-WASHING MACHINE.

To all whom it may concern:

Be it known that 1, Isaac L. FRANK'EM, a

citizen of the United States, residing at Indiana olis, in the county of Marion and State of 111C iana, have lnvented certain new and useful Improvements in Dish lvashing Ma- .chines, of which the following is a specifica tion. I

This invention has for its object to provide an improved dish-washing apparatus; and to vice shown in Fig. 1, taken on the dotted line 3 3 pl Fig. 3. Fig. 3 is a transverse vertical sectlonof same on a plane between the traveling carriage and the inner partition of the tank, taken onthe dotted line'Z '2 of Fig. 2; and

' Fig. 4 is "a.detail,.in enlarged cross-section, of

theftjub-ular way which supports the carriage and the adjacent wall of the tank.

";Like characters of reference indicate like parts throughout the several views. of the drawings.

5 represents the tank. in which my invention is operated, and 6 represents the legs suporting same. The tank is preferably divided liy means of the partition 7 into two compartments, in the larger one of which the dishes will be washed and in the smaller one of which they will be rinsed. Extending from the outer end wall of the larger tank to the partition7 and sumaorted thereby are the two parallel ways 8, here shown as being formed out of gas-pipe, which will be the preferred 'material for that use.

.\lounted on each of the tubular ways 8 are the two grooved wheels .l, having spindles which are mounted in the housings H). These latter have hanger extensions which are made fast to a horizontal bar 1. l. Secured to the said bars 1 l. are the three parallel bars 12, each of which. extendsdown from said bars 11 to within a suitable distance of the bottom 13 of the tank and then extend transversely across the tank parallel with said bottom in Specification of Letters Patent.

the manner as clearly shown in thedrawings. The vertical members. of said ,barsdl are braced by means of the diagonal bars 14.1:

15 is a basket, preferably formed out of woven wire, which will begtilled. with the dishes to be washed, and'the filled basket will be placed in the tank1 ipon the horizontal members of the bars 12. The longitudinal displacement of the basket. is prevented by the vertical standards 16, which are formed by bending up the freeends of bars, the body portions 17 o't'whicha-re laid upon the horizontal portions ofs aidbars 12 and are secured thereto to additionally brace and strengthen the basket holding structure. This device forms a carriagewhich is movable on the tubular ways 8, and the dishcleansing operation is accomplished by imparting a reciprocating movement to the carriage on said wa 's.

The tank will be filled with hot soapsuds so as to wholly or partially cover the dishes contained in the basket, and the impact of the water against the dishes as the carriage loaded with them serves to loosen and remove the foreign matter with which they are covered or soiled. The faster the carriage is moved back and forth in the water the greater the impact of the latter will be against the dishes and more rapidly they will be cleansed.

'20 is ahandle attached to the carriage, by means of which the latter will be moved.

Z1 is a drain-pipe which sewer, as shown in Fig. 2, and has its open mouth at the height otthe water-level in the tank for the purpose of draining oil the accumulation of grease that rises and floats upon the top of the water. 22 is a similar drain pipe in the rinsing-compartment of the tank, and both compartments have the valve closed drains 23 from their bottoms, which also communicate with the sewer tor the emptying of both tanks of their liquid contents.

After the dishes have been thoroughly washed in the large compartment the basket containing them is lifted out and is deposited in the rinsing-section oi the tank. 'lhere they are rinsed with clean hot water, and upon removal their heated condition. causes an evaporation which dries them without further labor.

Both compartments of the tank may be heated by burners 24, ted from. a gas-pipe 25 passing thereunder.

is moved to and fro therein connects with the Havin thus fully described my invention, what I c aim as new, and wish to secure'by Letters Patent of the United States, is' 1; Ina dish-Washing machine, a tank di- 5 vided by a partition into two compartments, apair-of horizontal and parallel tubular ways supported by'said partition and the end of the tank, pulleys or wheels mounted-on the tubular ways, housings within which said wheels are mounted, hangers depending from said housings, horizontal bars supported by said hangers, a lura'lity of bars fastened to said horizonta bars and-extending I thence down to near the bottom of the tank -15 and thence horizontally across the tank,

braces for said bars, a handle. attached to the carriage thus formed, and a removable dishholding receptaclefof'perforate material supported upon the horizontal members of sald plurality of bars. I

2. In a dish-washing machine, atank divided by a artition into two compartments, each of sai compartments having aseparate I tubular overflow, one of said compartments 25 havinga pair-of horizontal tubular tracks or ways,- each adjacent to op osite sides of its I tank andsupported from t e end of the tank" andfi'omsald partition, a pluralityof wheels mounted on each of said ,Ways, each of said wheelshaying a'hanger, horizontal bars sup- '0 ported by said hangers, other bars having their ends attached .to opposite ones of sai horizontal bars and extending first downwardly and then hoi'izontallyacrossithe tank, 3

handle extensionfrom thecarriage -thus o formed, and a'rece tacle of woven wire to re-.

ceive the dishes to e washed, said receptacle being removably, secured upon the carriage In witness whereof I have hereunto set my hand and seal, at Indianapolis, Indiana, this 45 3d day of January, A, DL- 1905.
